Nasal obstruction, otitis media with effusion, pain in the ear, hearing problems, and unusual neck mass are among the signs and symptoms of this malignancy.   Case Report: We report the case of a 13-year-old girl with NPC who later developed acute lymphoblastic leukemia (ALL) through the course of her disease. To our knowledge, this is the first report of ALL following childhood nasopharyngeal carcinoma in the English-language literature.   Conclusion: Reports of secondary malignancies at the site of radiotherapy for NPC exist, but this is the first report of ALL following NPC.
